This can cause the kernel to\ncrash due to a pagefault.\n\nFix it by setting ctx->fp_used = true for exception boundary programs as\nfp is always saved in such programs."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["arch/arm64/net/bpf_jit_comp.c"],"versions":[{"version":"5d4fa9ec5643a5c75d3c1e6abf50fb9284caf1ff","lessThan":"0dbef493cae7d451f740558665893c000adb2321","status":"affected","versionType":"git"},{"version":"5d4fa9ec5643a5c75d3c1e6abf50fb9284caf1ff","lessThan":"e23184725dbb72d5d02940222eee36dbba2aa422","status":"affected","versionType":"git"},{"version":"5d4fa9ec5643a5c75d3c1e6abf50fb9284caf1ff","lessThan":"1ce30231e0a2c8c361ee5f8f7f265fc17130adce","status":"affected","versionType":"git"},{"version":"5d4fa9ec5643a5c75d3c1e6abf50fb9284caf1ff","lessThan":"b114fcee766d5101eada1aca7bb5fd0a86c89b35","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["arch/arm64/net/bpf_jit_comp.c"],"versions":[{"version":"6.12","status":"affected"},{"version":"0","lessThan":"6.12","status":"unaffected","versionType":"semver"},{"version":"6.12.42","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.15.10","lessThanOrEqual":"6.15.*","status":"unaffected","versionType":"semver"},{"version":"6.16.1","lessThanOrEqual":"6.16.*","status":"unaffected","versionType":"semver"},{"version":"6.17","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.12","versionEndExcluding":"6.12.42"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.12","versionEndExcluding":"6.15.10"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.12","versionEndExcluding":"6.16.1"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.12","versionEndExcluding":"6.17"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/0dbef493cae7d451f740558665893c000adb2321"},{"url":"https://git.kernel.org/stable/c/e23184725dbb72d5d02940222eee36dbba2aa422"},{"url":"https://git.kernel.org/stable/c/1ce30231e0a2c8c361ee5f8f7f265fc17130adce"},{"url":"https://git.kernel.org/stable/c/b114fcee766d5101eada1aca7bb5fd0a86c89b35"}],"title":"bpf, arm64: Fix fp initialization for exception boundary","x_generator":{"engine":"bippy-1.2.0"}}}}
